The occurrence of a second malignant neoplasm (SMN) in patients who have been submitted to kidney transplantation is increasing and causes concern; parotid carcinoma is rarely reported after transplantation and may be related to long-term chemotherapy.Salivary gland carcinomas displaying exclusively myoepithelial differentiation-myoepithelial carcinomas (EMC) are rare, being less than 1% of all...

Castleman’s disease is a rare disorder characterized by benign proliferation of lymphoid tissue. Most cases occur as a mediastinal mass, although extrathoracic involvement including nodal and extranodal locations has been reported. The left suprarenal location of this localized disease may be mistaken for an adrenal tumor. We report a case of a 51-year-old woman with a Castleman’s tumor located...

We present a patient of tuberous sclerosis complex with bilateral renal angiomyolipoma and hepatic angiomyolipoma with spontaneous retroperitoneal hemorrhage from right angiomyolipoma (Wunderlich's syndrome). Nephron preserving approach was tried but the right kidney could not be salvaged. Hepatic angiomyolipoma was managed conservatively. Wunderlich's syndrome has been found in around 10% of c...

A 25-year-old woman was found a mass localized in the upper portion four years ago, and only slow progression in the past four years. She underwent a laparoscopic partial nephrectomy of right kidney and diagnosed as anastomosing hemangioma. On histology the vascular components of the tumor had an a...

Clear cell sarcoma of kidney (CCSK) is an aggressive renal neoplasm. We report two boys aged three and half, and three years with CCSK, one of whom had a disease free survival of four years and eight months. These patients were managed with surgery, chemotherapy and radiotherapy. One of the patients discontinued treatment early and lost to follow up. Aggressive multimodality therapy is the keys...

Congenital mesoblastic nephroma is a stromal neoplasm of infancy. It has been referred to as mesenchymal, cystic or leiomyomatous hamartoma. These tumors are centered around the hilus of the kidney. Mesoblastic nephromas need to be distinguished from other pediatric renal neoplasms as these lesions are treated by complete surgical excision without chemotherapy unless gross residual tumor remain...

Angiomyolipoma an uncommon benign neoplasm of the kidney is a triphasic tumour composed of angiomatous, smooth muscle and adipose tissue elements. They are usually associated with Tuberous sclerosis and commonly bilateral in presentation .Angiomyolipoma is often asymptomatic and is dedected incidentally in radiological studies and during autopsies. We present a rare case of a giant renal angiom...
